16 / 88 page  MPC862/857T/857DSL PowerQUICC™ Family Hardware Specifications, Rev. 3 16 Freescale Semiconductor Bus Signal Timing Table 7 provides the bus operation timing for the MPC862/857T/857DSL at 33 MHz, 40 Mhz, 50 MHz and 66 Mhz. The timing for the MPC862/857T/857DSL bus shown assumes a 50-pF load for maximum delays and a 0-pF load for minimum delays. Table 7.
